Description
Technical field
The present invention relates to one kind grab bucket, especially a kind of grab bucket with self-lubricate effect.
Background technology
Because grab bucket working frequency is high, so to hinge serious wear, it is necessary to often refuel, work effect can be not only reduced
Rate, can also increase the labor intensity and risk of workman, and hinge of now grabbing bucket refuels very inconvenient.
Grab bucket is usually operated at the operating modes such as harbour, soot very rugged environment, and nearby dust storm is larger for harbour, dust
Grain can block the oilhole of hinge, so that can not oiling.
The content of the invention
For the deficiencies in the prior art, the present invention provides a kind of grab bucket automatic lubricating structure, it can be ensured that hinge energy
The effect lubricated always is enough reached, and hinge oil nozzle can be fully sealed, the possibility of obstruction oilhole is eliminated.What the present invention was used
Technical scheme is：
One kind grab bucket automatic lubricating structure, including two limited blocks at the grab bucket back side in pairs are arranged on, in addition to：Spring, work
Plug, check valve, fuel tank, oil inlet hose, fuel-displaced flexible pipe；
A cavity is fabricated in the limited block, piston is put into cavity, between piston and limited block cavity bottom wall
If spring；The piston rod of piston at least exposes one section of cavity；
Fuel tank is connected with limited block cavity by oil inlet hose, and check valve is provided with by fuel tank one end in oil inlet hose；
Oil discharge passage is set on limited block bottom wall, and oil discharge passage is communicated with the oil out port of limited block bottom wall outer, it is spacing
The oil out port of block is connected by fuel-displaced flexible pipe with the oil nozzle of each hinge.
Further, oil groove is additionally provided with the inside of the oil discharge passage of limited block bottom wall, the diameter of oil groove is straight more than oil discharge passage
Footpath.
Further, hand switch is additionally provided with oil inlet hose.
The advantage of the invention is that：
1）It can ensure that grab bucket hinge is continuously obtained lubrication.
2）The influence of adverse circumstances is avoided, the oilhole of hinge will not be blocked by dust granules.
Brief description of the drawings
Fig. 1 is structure composition schematic diagram of the invention.
Fig. 2 is limited block of the invention and piston enlarged diagram.
Fig. 3 for Fig. 2 local A to schematic diagram.
Embodiment
With reference to specific drawings and examples, the invention will be further described.
The grab bucket automatic lubricating structure that the present invention is provided, as shown in figure 1, mainly for setting on 1 back side of existing grab bucket
Limited block 2 improved, its structure include spring 3, piston 4, switch 5, check valve 6, fuel tank 7, oil inlet hose 8, oil nozzle
9th, fuel-displaced flexible pipe 10；Existing grab bucket 1 is typically to be arranged in pairs, and the oil nozzle 9 in Fig. 1 is the oil nozzle on hinge.
A cavity is fabricated in the limited block 2, piston 4, piston 4 and the cavity bottom wall of limited block 2 are put into cavity
Between set spring 3；The piston rod of piston 4 at least exposes one section of cavity；
Fuel tank 7 is connected with the cavity of limited block 2 by oil inlet hose 8, and check valve 6 is provided with by fuel tank one end in oil inlet hose 8,
Hand switch 5 is additionally provided with oil inlet hose 8；Lubricating oil can be stored in fuel tank 7.
Oil discharge passage 201, and oil discharge passage 201 and the oil out port 202 of limited block bottom wall outer are set on the bottom wall of limited block 2
Communicate, the oil out port 202 of limited block 2 is connected by fuel-displaced flexible pipe 10 with the oil nozzle 9 of each hinge；Fig. 1 is schematic diagram, fuel-displaced
Passage 201, oil out port 202, oil groove 203 is not drawn, refers to Fig. 2.
Further, the inner side of oil discharge passage 201 of the bottom wall of limited block 2 is additionally provided with oil groove 203, and the diameter of oil groove 203 is more than
The diameter of oil discharge passage 201, the purpose for making oil groove prevents pressure is uneven from causing indivedual hose pressure deficiencies to normally complete
Oiling is acted.
When grab bucket 1 open when or so two limited blocks 2 bump against the piston rods of extrusion pistons 4 and complete to refuel, lubricating oil is from limit
Oil discharge passage 201 is squeezed out in the cavity of block 2 of position, two limited blocks 2 are separated when being closed when grabbing bucket, and piston rod is ejected and completed by spring 3
Lubricating oil in fuel tank 7 is sucked the cavity of limited block 2 by the reset of piston rod simultaneously.Move back and forth the action for being formed and continuously being refueled.
It is before grab bucket can work daily plus once oily, once add a hour or more long.Oil inlet hose is opened when refueling
On switch 5.Because grab bucket operating mode is severe, oilhole can be blocked, oil hose can be directly accessed the oil of hinge by this device
Mouth formation sealing, it is to avoid the possibility that oilhole is blocked.
